VerifyError #1025 - default xml namespace and getter function

Question

I have narrowed the problem down to a a few lines. I have
created a simple example of the problem...
// TestClass.as
package {
import flash.events.EventDispatcher;
public class TestClass extends EventDispatcher {
private var _testVar:String;
public function TestClass() {
var testXML:XML = <node1 xmlns="
http://www.testurl.com/"><node2><node3>some
words of wisdom</node3></node2></node1>;
default xml namespace = testXML.namespace("");
_testVar = testXML.node2.node3;
public function get testVar():String {
return _testVar;
// Test.fla - frame 1
import TestClass;
var myTestClass:TestClass = new TestClass();
var someVar:String = myTestClass.testVar;
trace(someVar);
I get the following error...
verify TestClass/get testVar()
stack:
scope: [global Object$ flash.events::EventDispatcher$
TestClass$]
locals: TestClass

stack: TestClass

TestClass$]
locals: TestClass
1:pushscope
stack:

locals: TestClass
2:getlocal1
VerifyError: Error #1025: An invalid register 1 was accessed.
at TestClass/get testVar()
at Test_fla::MainTimeline/Test_fla::frame1()
However if I take out the default xml namespace line, and
create a new namespace it will work.
var testNS:Namespace = new Namespace(testXML.namespace(""));
_testVar = testXML.testNS::node2.testNS::node3;
Thoughts??? It's driving me crazy. Thanks in advance...

The attribute should be in the element's namespace. If I run this snippet on the timeline, it outputs the correct values.
var xml:XML =
<xml>
<animal type="sheep" xmlns="http://blabla">
  <name>josh</name>
  <age>2</age>
</animal>
<animal type="cow" xmlns="http://blabla">
  <name>jim</name>
  <age>2</age>
</animal>
</xml>
var ns:Namespace = new Namespace("http://blabla");
default xml namespace = ns;
trace( xml.animal.@type ); // OUTPUT: sheepcow
